A fish ladder, also known as a fish way, fish pass or fish steps, is a structure around dams to facilitate fishes' migration. Typically, the observation windows are integrated into the ladder. Here, the fish are forced into narrower streams and the fish will need to swim close to the window, which makes observation easier. The structures consist mainly of concrete.
